This paper presents a new and very rich class of (con-current) programming languages, based on the notion of comput.ing with parhal information, and the con-commitant notions of consistency and entailment. ’ In this framework, computation emerges from the inter-action of concurrently executing

. Students who eventually dropped out had greater intentions to drop out of school early in the school year than did those who persisted. A gender main effect was also obtained, F(l, 4521) = 11.58, p < .001. Male students reported higher dropout intentions than female students. The interaction

Abstract. We assign to each positive variety V and a fixed natural number k the class of all (positive) boolean combinations of the restricted polynomials, i.e. the languages of the form L0a1L1a2... a`L`, where ` ≤ k, a1,..., a ` are letters and L0,..., L ` are from the variety V

Nanomaterials are part of an industrial revolution to develop lightweight but strong materials for a variety of purposes. Singlewall carbon nanotubes are an important member of this class of materials. They structurally resemble rolled-up graphite sheets, usually with one end capped; individually

Abstract. We assign to each positive variety V and a fixed natural number k the class of all (positive) boolean combinations of the restricted polynomials, i.e. the languages of the form L0a1L1a2... aℓLℓ, where ℓ ≤ k, a1,..., aℓ are letters and L0,..., Lℓ are from the variety V. For this polynomial

Microalgae are used in mariculture as live feeds for all growth stages of molluscs, for the larval stages of crustaceans and some fish species, and for zooplankton used in mariculture food chains. In order to be nutritionally sufficient, microalgae must supply a balanced mixture of nutrients. We

Parametric max-stable processes are increasingly used to model spatial extremes. Since the dependence structure is specified for block maxima, the data used for inference are block maxima from all sites. To improve the estimation efficiency, we propose a two-step approach with composite likelihood that utilizes site-wise daily records in addition to block maxima. Besides the parameter estimation, there is no formal model checking and diagnosis method for spatial extremes modeling yet. Model diagnosis in practice has been informal and mostly based on visual checking tools such as residual plot and quantile-quantile plot. We proposed a goodness-of-fit test for max-stable processes based on the comparison between a nonparametric and a parametric estimator of the corresponding unknown multivariate Pickands dependence function. The proposed two-step procedure separates the estimation of marginal parameters and dependence parameters into two steps. The first step estimates the marginal pa-rameters with an independence Likelihood by ignoring the spatial dependence. Given ithe marginal parameter estimates, the second step estimates the dependence parameters

Abstract. We define (with machine-checked proofs in Coq) a modular operational semantics for Concurrent C minor—a language with shared memory, spawnable threads, and first-class locks. By modular we mean that one can reason about sequential control and data-flow knowing almost nothing about
